mtg basic land cards Set - Zendikar Mint / near mint condition trading card A Deep Dive on Eldraine's

Decanter of Endless Water goes in most decks that care about Thought Vessel, for example

She makes mana

The second ability lets you immediately exert any character you play that costs 2 or less ink

For each other result, it gains the indicated ability until end of turn

This creates a value loop where you get your ETB triggers twice, once for the original and once for the token, all for a massive discount in mana

Eventually we assemble a combo like Vadrik, Astral Archmage + any R generator like Storm-Kiln Artist + Searing Touch for infinite damage, or Electrodominance copied with Reiterate (w/ buyback) for infinite damage
